区域气候模式和大气化学模式对中国地区气候变化和对流层臭氧分布的模拟

Using Regional Climate Model and Atmosphere Chemical Model to Model Regional Climate and Ozone in Troposphere over China

在区域气候模式的基础上引入了对流层大气化学模式 ,并实现两者的双向反馈连接 ,利用该模式系统模拟中国地区对流层大气臭氧和区域气候 ,发现东亚季风是影响中国地区对流层大气臭氧分布的重要原因 ,并且对流层臭氧分布局域性较为明显 .模拟也得到了模拟区域气候的四个典型月特征 ,并与分析资料对比验证了所得结果 .此外利用大气化学模式计算的臭氧反馈到区域气候模式中 ,模拟对流层臭氧增加背景下 。

An atmospheric chemical model has been coupled with a regional climate model in order to simulate the regional climate and ozone in troposphere over China. On the basis of the modeling, it has been found that East Asia monsoon is one of the dominant factors that can deeply affect ozone distribution in troposphere. The ozone in troposphere can be affected by other factors such as complex terrain and pollutant. The radiative forcing at the top of atmosphere of clear sky has also been explored with the chemical coupled regional climate model system.
